This study aims to evaluate the effectiveness of FlipaClip as a learning media, and to compare the problem-solving abilities of students who learn using FlipaClip and PowerPoint. This study employed the ADDIE development paradigm (Analysis, Design, Development, Implementation, and Evaluate) as a framework for research and development (R&D). The findings demonstrated the validity and viability of learning media that use a contextual approach to linear program content. With extremely valid criteria, the material validation findings came out at 84.38%. The validation results from media experts were 94.79%, which is considered highly valid. Although the student response received an assessment percentage of 83.64%, the response also met the FlipaClip-based learning media's "very interesting" requirements, indicating that it is practical to use. Moreover, the research shows that FlipaClip-based learning media on program material can improve the mathematical problem-solving ability of class XI students. Quantitatively, the difference is shown by the interpretation of N-Gain obtained in the experimental class, which is quite an effective category with a percentage of 70.22%. The average mathematical problem-solving ability of grade XI students who are given FlipaClip-based learning media is higher than the average student who is not given the media, as indicated by the results of the independent sample t-test, namely the Sig. (2- tailed) value of 0.000 <0.05.

Critical thinking and political literacy are essential competencies in 21st-century education; however, they are often developed separately in school learning. This study investigates the relationship between mathematical critical thinking ability and students’ political literacy at the senior high school level. Using a quantitative correlational design, data were collected from 80 eleventh-grade students selected through stratified random sampling from three public high schools in Yogyakarta City. The instruments consisted of a mathematical critical thinking test and a political literacy questionnaire, both of which demonstrated acceptable validity and reliability. Data were analyzed using the Pearson Product–Moment correlation. The results revealed a significant positive correlation between mathematical critical thinking and political literacy (r = 0.58, p < 0.01), indicating that students with stronger mathematical reasoning tend to exhibit higher political literacy, including a better understanding of democratic values and more rational civic attitudes. These findings demonstrate that mathematical critical thinking contributes meaningfully to students’ political literacy. The study highlights the importance of integrating socio-political contexts into mathematics instruction as an interdisciplinary approach to fostering analytical and responsible citizenship in a democratic society.

Kemampuan pemecahan masalah geometri menuntut ketelitian, keterampilan berpikir logis, dan reflektif. Namun, banyak siswa di jenjang Sekolah Menengah Pertama (SMP) memiliki gaya kognitif impulsif, yaitu kecenderungan menjawab dengan cepat tanpa analisis mendalam sehingga sering melakukan kesalahan konseptual maupun prosedural. Kegiatan pengabdian ini bertujuan untuk meningkatkan kemampuan pemecahan masalah geometri siswa impulsif melalui program pendampingan belajar berbasis reflektif. Kegiatan dilaksanakan di salah satu SMP mitra dengan melibatkan 15 siswa kelas VIII yang diidentifikasi memiliki gaya kognitif impulsif menggunakan instrumen Matching Familiar Figures Test (MFFT). Metode pelaksanaan meliputi empat tahap, yaitu: (1) identifikasi karakteristik siswa impulsif, (2) pelatihan berpikir reflektif dan strategi penyelesaian masalah geometri, (3) pendampingan belajar kelompok kecil menggunakan lembar refleksi berpikir berbasis langkah Polya, serta (4) evaluasi hasil dan refleksi bersama. Hasil kegiatan menunjukkan adanya peningkatan kemampuan siswa dalam memahami masalah, menyusun strategi, serta memeriksa kembali langkah penyelesaian. Selain itu, siswa mulai menunjukkan perubahan perilaku belajar yang lebih hati-hati dan sistematis. Guru mitra juga memperoleh pemahaman baru mengenai pendekatan pembelajaran reflektif yang sesuai dengan karakteristik siswa impulsif. Dengan demikian, pendampingan reflektif terbukti efektif membantu siswa impulsif mengembangkan kemampuan pemecahan masalah geometri secara lebih terarah dan mendalam.

Career information services are widely implemented in secondary schools to support students’ career decision-making; however, empirical evidence regarding their direct effectiveness remains inconclusive. This study examines the mediating role of career maturity in the relationship between career self-efficacy, parental social support, career information services, and career planning decisions among senior high school students. A quantitative cross-sectional design was employed with data collected from 200 students through validated and reliable questionnaires. Path analysis using LISREL was conducted to test direct and indirect effects. The findings reveal that career self-efficacy, parental social support, and career information services significantly predict career maturity. Career maturity shows the strongest direct effect on career planning decisions. Notably, career information services do not directly influence career planning decisions but exert a substantial indirect effect through career maturity. These results suggest that providing career information without strengthening students’ career maturity may limit the effectiveness of career guidance programs. This study contributes to career development literature by empirically demonstrating the central mediating function of career maturity in adolescents’ career decision-making and offers practical implications for school-based career guidance interventions.
